Description

Main Features:
This app includes zoomable diagrams for the Chicago 'L' Train.
Maps work underground even if there is no connection to the internet!
The maps will automatically update when a newer map is avaiable (requires network connection).
The maps are given the entire screen! We don't use tabbed views and other navigation mechanisms that take up valuable real estate. A costom slide-out menu design is used.
Smooth scrolling and zooming
